**4. Conclusions**

This study discussed the effects of a magnetic field on the flow of Sisko fluid containing gold nanoparticles over a porous, curved surface in the presence of radiation and partial slip. The key outcomes were as follows:


• When suction increases in the curved wall surface, both the temperature and the velocity of blood decrease.

The current theoretical estimates will be significant for the more precise treatment of patients with regard to better outcomes of thermal therapy for reducing pain. In addition, this investigation will improve the understanding of thermal processes that occur during blood flow in arterial microvessels. Clinicians involved in tumor and cancer treatment will begin using the electromagnetic hyperthermia technique, which involves overheating target tissues to about 42 ◦C. The results show that the flow velocity of blood can be managed by suitably adjusting (decreasing/increasing) the magnetic field intensity. This finding should help surgeons who generally want to maintain blood flow at a preferred level throughout surgery.
